To all whom itm'ay concern:

Be it known that We, EDWARD J. BoWLns,

ELMni: Mnrz' and HERMANMETZ citizens" of the'United States, residentsof'Clinton, in

the county of Dewitt and State ofIllinois,

object of our invention is the provision of a" sim'ple and eflicientmechanismofthat type which will bead and form gutters or troughs withfacility;

A'further obj ect is' the provision of ad'e vice of this character inwhich a'sheet ofmetal may be placedand beaded and then formed into asuitable-gutter or trough, provision'being made for suitableadjustments, wherebytrougl'is i and gutters of dlfierent" sizes may bemade in one and the same ma cl11ne.' r

A further o'bjectis the pr'o'vlsion of a de viceof this'charactenwhichii'iclud'es 'a formbig-trough, a.*tubular-for1n mounted and adapted'tobe pressed into saidtrOugh, a"

beadingrodmounted on one'side of said trough and an additional formonthe other side of said trough, adapted to complete'the forming "of thegutter.

A" further object of our 'inventionis the' provision of a trough havingmeans i for varying its size and having a beading rod mo'unted" ad acentone side thereof, a

forming cylinder pi votally and removably mounted on the same side ofsaid trough and adapted to be forced into said trough to shape a sheetof metal, and an additional form on the other side'of said troughadapted to' be'mov'ed over said 'forn'iing cylinder to complete theshaping of the gutter or trougl'r section.

To the accomplishment of the foregoing and 'such' other objects as mayhereinafter appear, our invention consistsin the combi nation,constri'ictio'n and arrangements of parts'hereinafter described, andthen sought to bedefined in the appended claims, reference beinghad tothe" accompanying drawings fornnng a part hereof, and which show merelyfor the purpose,ofillustrative disclos'l'lrefa preferred embodiment ofour invention, it being understood that various changes maybe made inpractice Within the scope of the claims, Without digressin'g from ourinventive ldea;

In'the draw1ngs Figure 1 represents a; perspective view'of a machineconstructed according to our invention, position;

Fig. 3 is a detail View of the means for operating and locking thebeadiifgrod.

Referring now to the drawings, the nu- .meral'l designates the legs orsupports, on which is mounted the base member 2 which is shown in theform of a channel and has the trough 3 mounted thereon.

one of'said angle members having the bolts 5 which pass through slots 6'in the channel member 2'h'aving the securing nuts 7 and" Which willhereinafter cured-to the vertical flange of the angle trough by' meansof the member 4 ofthe wing nuts and b'o'lts 14, which permit thereadyremoval of the member 13in caseof accident;

Secured to the channel member 2 anglemember4 are th'e bracket members 15Which extend upwardly and pii' otal ly sup port the elongated I Theseoperating levers 16 are pivotall'y con-' nected as at 17 to themember 18secured to the forming roll '20,

the'forni" of an elongated tube. This form'- ing roll isad'apted' to bemoved to'and from the positiOnshown in Fig. 2 of the drawing,

by means of the operating levers 16, soas to the forming roll being informing This trough is formed of two angle members at and 4',

varyingthe'size ofv the l and the operatinglevers 16 w v between thepairs of spaced lugs19, this member 18 being" which is in operate on asheet metal blank and press the Secured to the other side of the channelmember 2 are the extended arms or bracket members 21 which support theguiding means I with the head 27. This guiding member also has thedepending lug or projection 28 adapted to bear against the stop member29 which may be placed at different positions on said arm or bracketmember so as to adjust the position of the guide-members, and limittheir movement inwardly. The stop members 29 comprise merely a rod,shaft or pin positioned in one of a number of apertures or holes in saidbracket members.

Secured to the lug or projection 28 is the spring 30 which is alsosecured to a lower portion of the arm or bracket 21, whereby the guidemember is normally held toward the trough. The handle 31 is providedthereon so that it may be manually withdrawn. The arm or bracket member21 is provided with the inclined and extended portion 21 on which theguiding member is mounted, the inclination being at a suitable angle togive the best results.

We mount on the same side of the trough as the guide members, theadditional forming element 32, which is in the form of the angle member33 having the operating arms or levers 34 secured thereto. Thisadditional forming element is hinged to the angle member 4 of the troughby means of a plurality of hinges 35 and has secured thereto, theplurality of curved lugs or wings 36, which pass through suitable slotsin the angle member 4 of the trough to a position within the trough tobe engaged by the sheet metal blank when pressed downwardly by theforming roll 20. This will throw the operating levers 34 out to aposition for convenient manipulation.

The beading rod is loosely mounted in the housing 10 and has the cranks37 for operation. One of the cranks is provided with the flange 38 whichis adapted to be engaged by the hooked lug 39 which is pivoted at 40 tothe side of the trough and normally held in locked position as indicatedin Fig. 3. This prevents the displacing of the beading rod wheninserting the sheet metal blank.

The operation of forming and beading a gutter section will now beexplained. Assuming that the parts are in the position shown in fulllines in Fig.2, a sheet metal blank of suitable width is inserted withone edge in the groove 12 in the beading rod, the guide membershavingbeen withdrawn manually so that the other edge engages in the Irollers 24. The cranks 37 are then manipulated to formthe bead on oneedge of the sheet metal blank, and the operating levers 16 are thenmoved to the dotted line position trough,

of Fig. 2 and full line position in Fig. 1, which forces the sheet metalblank into the causing it to conform to the cross sectional shape of theroll 20. During this operation, the curved lugs or wings 36 are engagedby the sheet metal blank and cause the additional forming element andits operating levers 34 to move outwardly and upwardly so that they maybe readily grasped by the operators, who then lift the levers 34,moving'the parts to the dotted line position of Fig. 2, thereby forcingthe free edge of the sheet metal blank around the roll 20. The parts arethen returned to their full line position in Fig. 2 and the completedguttersection withdrawn, completely beaded and formed. I

As has been stated hereinbefore, the machine is adapted for theformation of Various sizes ofgutter sections and for that purpose, thewidth of the trough may be varied, by means of the connectiondescribedfor adjusting the position of the angle mem ber 4. Spacing blocks 41 areinserted where necessary, and a roll 20 of the proper size is attachedto the lever 16, it being understood that the pivotal connection 17 isreadily detachable. The guide members 22 are adjusted on the inclinedportion 21 of the arm or bracket members 21, so as to accommodate the,variation in width of the sheet metal blank.

It is therefore seen that we have provided I.

a mechanism which is simple in structure and operation, capable ofvarious adjustments to form and bead diiferent sizes of gutter sections.In case the blank buckles about the beading rod, the housing 10 may bereadily removed.
